The rear panel is secured to the front case by eleven clips permanently attached to the rear panel. These clips lock onto small tabs machined into the front case.

To free the tabs, they must be pushed down and away from the iPod's case. Note the location of all tabs on the rear panel. When using an iPod opening tool to free the rear panel, be sure to work the tool at the location of these clips.

Opening the iPod can be challenging. Don't get discouraged if it takes you a few tries before the iPod is opened.

Insert the large iPod opening tool into the seam between the front case and rear panel of the iPod, below the dock connector. Run the tool back and forth to create an opening. The tool's edge should point toward the rear panel to prevent any accidental scratching of the aluminum front case.

The large iPod opening tool is no longer needed to gain access to the left side of the iPod.

Gently enlarge the existing gap by pressing/wiggling the small iPod opening tool into the gap near each of the two tabs attached to the rear case, pushing the clips toward the center of the iPod until both have been freed.

The ends of the battery leads are fed through small holes in the logic board and held in place by a small amount of solder.

Begin by heating the exposed end of the white battery lead with the tip of a soldering iron while simultaneously pulling the lead away from the connection, using tweezers to grasp the lead by the insulation.

De-solder the remaining leads, following the procedure illustrated above.

Due to the delicate nature of electronic components, it is imperative to limit the amount of heat transferred from the soldering iron to the logic board. An easy way to accomplish this is to pull on the battery lead with light, continuous tension, while the soldering iron heats up the connection. In order to avoid damage, lift the solder tip off the connection as soon as the solder melts and the lead slides out.

To aid in soldering the new battery, be sure the solder pad holes are clear of solder. This way, you can insert the new battery leads and solder them in place.

To open the solder holes, open a safety pin and push it against the solder blocking the hole. At the same time, heat the same solder pad from the other side of the logic board. Opening the holes completely will require repeating this procedure several times from alternating sides of the logic board.

These holes are extremely small, so the safety pin will probably be too large to pass all the way through. Do not insert the entire pin through the hole -- only the tip of the pin.

You can also try entering the tip of the pin on the other side of the board to open the solder pad hole.

In this step, you will solder the battery leads to the solder pads on the logic board.

Excess heat transferred to the logic board while soldering may result in electronic component damage. As a rule of thumb, hold the tip of the soldering iron against the joint just long enough to melt the solder, then quickly remove it.

Solder the connection by momentarily placing the tip of the soldering iron against the connection, melting solder into the connection, and quickly removing both the solder and the tip of the soldering iron from the connection. The solder should flow around the new battery lead, solidly connecting it to the pad on the logic board.

Solder the other two battery leads in the same fashion, taking care not to bridge any of the connections together.

Step 19> when un-soldering the old battery wires, make sure to leave solder on the pads and in the holes.

I replaced steps 22-24 with Step 22-24> Very carefully and precisely:

-Place the black lead onto the pad nearest the hold switch (shown in red) with the end of wire pointing away from the battery.

-Place the red lead onto the center pad with the end of wire pointing away from the battery.

-Place the white lead onto the pad furthest from the hold switch with the end of wire pointing away from the battery.

Gently hold each wire in place on the pad while applying the soldering iron taking care not to touch the wire to any other pad or trace (note black wire). When the wire sinks into the solder, remove heat. Hold wire until solder has set.

Success! The instructions were clear and helpful. This was the third battery for my iPod, so the desoldering step took a fair amount of time. I am not very experienced with soldering, so I practiced on a little blinking christmas tree kit before attempting this, and I think that was useful.
